Range Rover Velar - Engineering

Post by Rob » Wed Mar 01, 2017 8:48 pm

3. WORLD-CLASS ENGINEERING

Engineering integrity is at the heart of every Land Rover. Engineered in the UK and developed and tested in the harshest conditions around the world, Velar upholds that core philosophy. The result is a mid-size luxury SUV that provides outstanding dynamics and refinement, unparalleled all-terrain capability and total dependability.

3.1 Outstanding capability on- and off-road

Velar’s advanced chassis offers the ultimate in comfort, dynamics and all-terrain capability. The sophisticated double-wishbone front suspension follows sports car design principles, with knuckles and bearings engineered for particularly high stiffness to deliver exemplary steering and handling response and precision. Aluminium is used extensively to save weight, while steel front lower control arms provide maximum durability in challenging off-road conditions.

An Integral Link rear axle with forged aluminium toe links and upper control arms delivers the high lateral stiffness needed for exceptional handling precision, together with the longitudinal compliance needed for outstanding ride comfort and refinement. Integral Link is the most sophisticated and most capable rear suspension system available, and the design is also highly space-efficient, minimising intrusion into the luggage compartment

The suspension systems also offer outstanding wheel articulation and ensure that Velar can outperform the competition no matter what the terrain. With an approach angle of up to 28.89 degrees, breakover angle of up to 23.5 degrees and a departure angle of up to 29.5 degrees, and a maximum wading depth of 650mm (600mm for coil spring suspension), Velar sets new standards for off-road capability in the mid-size SUV segment.

Velar is offered with coil springs as standard on four-cylinder models, and a ground clearance of 213mm. Four-corner air suspension as an option on the four-cylinder 240PS diesel and 300PS petrol, and as standard on all six-cylinder models. This system delivers truly outstanding comfort and significantly increased off-road capability.

The air suspension’s ride height drops by 10mm when cruising at speeds above 65mph (105km/h) to reduce aerodynamic drag and therefore improve fuel efficiency. The Auto Access Height function automatically lowers the suspension by 40mm when the ignition is turned off, making it easier to get in and out of the vehicle.

Off-road mode increases the ride height by 46mm compared to Normal mode at speeds below 32mph (50km/h) for a class-leading ground clearance of 251mm, but automatically lowers by 18mm between 32-50mph (50-80km/h) () to provide an ideal combination of stability, comfort and ground clearance during longer journeys on rutted, unpaved roads or surfaces.

The air suspension also helps drivers when wading too. The Grounding Detection function can automatically raise the vehicle to help clear underwater obstacles which the driver may not have been able to see. The additional ground clearance can be requested by pressing the brake pedal and a button on the touchscreen. And because air suspension is self-levelling, it maintains the optimum ride height when towing or carrying heavy loads, improving occupant comfort. It also brings benefits when hitching a trailer, or when loading or unloading: controls inside the luggage compartment allow the suspension to be raised or lowered by 50mm respectively.

Adaptive Dynamics is standard on all models. By monitoring wheel movement 500 times per second, and body movements 100 times per second, the system continuously varies the damping forces at all four corners of vehicle. This ensures that suspension stiffness is optimised for the driving conditions, improving ride comfort and handling – there’s even a specific calibration for off-road driving.

Configurable Dynamics: a tailored driving experience

Standard on First Edition models and available across the range, Configurable Dynamics allows the driver to tailor vehicle settings to their individual preference using the touchscreen. In Dynamic mode’s default setting, throttle response is increased, gear shifts anticipate a sportier driving style, the suspension stiffens and power-steering assistance is reduced for extra driver feedback. Configurable Dynamics allows each parameter to be individually adjusted, so increased throttle response can be combined with, for example, the default suspension setting.

Dynamic information is also displayed in the touchscreen and shows g-force, stopwatch and the throttle pedal activation, helping enthusiasts to make the most of their driving experiences.

Electric Power-Assisted Steering: response and efficiency

Velar’s electric power-assisted steering (EPAS) system has been developed for exceptional driver feedback, precision and feel. Optimised friction and inertia compensation algorithms ensure completely intuitive steering responses, and an active return system promotes a natural self-centring effect as the steering returns to the straight-ahead position. The variable-ratio system also ensures that the driver benefits from greater responsiveness the more they turn the wheel.

EPAS improves efficiency as well as the driving experience: because it only uses energy when the wheel is turned, it can cut fuel consumption by as much as three per cent on the European combined cycle compared to hydraulic systems.

The Torque Vectoring by Braking (TVB) system, standard on all models, further enhances agility. If the system detects the onset of understeer during corner entry it can initiate light braking of the inside wheels – in particular the inside rear – to help the driver to maintain an ideal line through the corner. TVB is also beneficial at lower speeds when driving on slippery surfaces such as mud or snow.

Unrivalled capability: All-Wheel Drive system and traction technologies

Velar is equipped with a range of advanced technology to deliver exceptional composure and agility on-road, and class-leading capability off-road.

The most significant of these is an intelligent, efficient, torque on-demand all-wheel-drive (AWD) system, which provides the optimum torque distribution to suit the conditions, whether dynamic driving on tarmac roads or pulling away on polished ice.

The system is built around a single-speed transfer case featuring a multi-plate wet clutch and a chain drive to the front axle. Designed to be compact and quiet in operation, the transfer case’s main advantage is its speed: depending on conditions it can make the transition from 100 per cent rear bias to fully locked in only 165 milliseconds; transient torque delivery to the front axle can take as little as 100 milliseconds. This makes the AWD system incredibly responsive, which delivers exceptional performance in all conditions.

Torque distribution between the front and rear axles is managed by Intelligent Driveline Dynamics (IDD), a highly-sophisticated control system developed in-house. IDD takes information from a number of sensors around the vehicle, including steering wheel angle, throttle position, yaw rate and lateral acceleration. Using this data, IDD continuously estimates the friction between the tyre contact patch and the surface – and how much of the available grip is being exploited.

With this level of intelligence, IDD can use both pre-emptive and reactive control strategies in order to optimise torque distribution, maximising traction and also enhancing vehicle dynamics. To make IDD even more effective, it is networked to the vehicle’s Dynamic Stability Control system, Torque Vectoring System and – where fitted – the Active Locking Rear Differential.

The Active Locking Rear Differential, which is available on all six-cylinder models, also delivers benefits on- and off-road. Electronic control of the wet clutch pack means that the differential can optimise the torque distribution between the rear wheels as a function of load transfer and surface friction: this maximises traction during launch and corner exit, and when traversing challenging off-road terrains.

Land Rover’s world-leading Terrain Response system allows the driver to adjust vehicle settings to suit prevailing surface conditions, with a choice of Eco, Comfort, Grass-Gravel-Snow, Mud-Ruts, Sand, and – on R-Dynamic models – Dynamic mode. Each alters the calibration of the engine, transmission, all-wheel drive system, suspension, and stability control systems for optimum traction and composure.

The even more advanced Terrain Response 2, standard on First Edition models and available as an option on all others, also has an automatic setting to make it even simpler for drivers to fully exploit the vehicle’s capability because it automatically selects the best Terrain Response mode for any given surface.

In a Land Rover-first, the Terrain Response systems are accessed not through a dedicated controller but using the driver’s reconfigurable infotainment system rotary controller, or directly through the touchscreen itself. This intelligent system integration contributes to the clean, uncluttered design of the centre console.

A comprehensive portfolio of off-road technologies supports Velar’s class-leading all-terrain capability. All Terrain Progress Control (ATPC) , also standard on First Edition models and available as an option on all others, functions like a low-speed cruise control and provides added composure in adverse conditions by managing vehicle speed, allowing the driver to concentrate solely on steering the vehicle – use of the throttle and brake is not required. The system is activated with the press of a button, and the desired speed set using the cruise control switches on the steering wheel.

ATPC works in both forward and reverse gears and is operational from 2.2mph to 18mph (3.6km/h to 30km/h) (). It is particularly beneficial in challenging off-road environments where a constant crawl speed is desirable in order to maintain vehicle composure and occupant comfort.

Low Traction Launch is designed to help drivers pull away smoothly from a standstill on very slippery surfaces. Activated through the infotainment system’s lower touchscreen, Low Traction Launch provides a very progressive throttle pedal calibration, reducing the possibility of wheelspin. Above 18mph(30km/h), the throttle calibration automatically reverts back to the Terrain Response setting that was previously selected.

Hill Descent Control (HDC) uses the ABS system to maintain a controlled vehicle speed on steep inclines without driver intervention. HDC incorporates Gradient Release Control to progressively release the brakes when moving away on an incline.

The latest development of the 4x4i menu offers slope information – displaying the degree of incline and front and rear camera views – as well as familiar information such as steering wheel angle, driveline torque distribution, suspension articulation, and Wade Sensing data.

3.2 Refined and efficient powertrains

Every one of the six petrol and diesel engines offered in Velar is engineered for the ideal blend of performance, refinement and efficiency and meets stringent Euro 6 emissions regulations. All are matched to smooth-shifting eight-speed automatic transmissions and all-wheel drive to deliver the effortless, composed driving experience synonymous with all Range Rover vehicles.

Ingenium diesels: Low fuel consumption, high torque

Two versions of Jaguar Land Rover’s clean, refined four-cylinder Ingenium diesel are offered, each delivering high levels of torque from low engine speeds, ensuring excellent responsiveness and acceleration whenever the driver demands it. Features such as the highly rigid crankcase, twin balancer shafts and active fluid-filled engine mounts ensure superb refinement.

Both of these 2.0-litre engines share the same inherently efficient, low friction design, and benefit from features such as a split-cooling system and electronically-controlled coolant pump for rapid warm-up and therefore reduced fuel consumption. Variable exhaust cam timing helps the aftertreatment system to reach operating temperature as quickly as possible, reducing emissions.

And both feature state-of-the-art technologies to cut NOx emissions. The sophisticated exhaust gas recirculation (EGR) system uses a cooled low-pressure circuit in addition to a high-pressure circuit: this reduces pumping losses, and therefore increases efficiency still further, and also reduces peak combustion temperatures to help reduce the formation of NOx in the cylinders.

The selective catalytic reduction (SCR) system cuts tailpipe emissions of NOx to very low levels. The system injects AdBlue diesel exhaust fluid into the exhaust gas, where it reacts with the NOx and converts it into harmless nitrogen and water, ensuring that the Ingenium diesels comply with the stringent limits of Euro 6.

The most efficient version of the engine, known as D180, features a 1,800bar common-rail system and a single variable geometry turbocharger, ensuring clean, quiet efficient combustion and excellent response from low engine speeds. Developing 180PS and maximum torque of 430Nm from 1,750rpm, this engine delivers flexible performance and outstanding efficiency: acceleration from 0-60mph in 8.4 seconds (0-100km/h takes 8.9 seconds) , with fuel consumption and CO2 emissions of 52.5mpg (5.4-litres/100km) and 142g/km respectively on the European combined cycle.

For greater performance without sacrificing efficiency, drivers can choose the more powerful Ingenium diesel: the D240. Equipped two turbochargers – Jaguar Land Rover’s first application of a series-sequential boosting system – and a 2,200bar common-rail system, this engine produces 240PS and an exceptional 500Nm of torque from just 1,500rpm. This enables acceleration from 0-60mph in only 6.8 seconds (0-100km/h 7.3 seconds. Figures of 48.7mpg (5.8-litres/100km) and 154g/km CO2 are equally impressive.

Extraordinary torque: V6 diesel with 700Nm

The latest 3.0-litre V6 diesel – the D300 – delivers benchmark refinement with exceptional efficiency and outstanding performance, thanks to a potent 300PS and astonishing maximum torque of 700Nm. This remarkable engine can take Velar from 0-60mph in only 6.1 seconds (0-100km/h in 6.5 seconds) on the way to a maximum speed of 150mph (241km/h). Fuel consumption and emissions figures are 44.1mpg (6.4-litres/100km) and 167g/km CO2.

This combination of power and efficiency is enabled by a package of advanced technologies. The 2,000bar piezo common-rail system ensures highly precise injection for optimised atomisation and mixing of the fuel droplets, boosting output and reducing emissions.

Response from the innovative parallel-sequential turbocharging system has been improved with highly optimised compressor wheel, turbine and variable nozzle designs, delivering even stronger torque output at lower engine speeds. State-of-the-art ceramic ball bearings are used in the primary turbo to reduce friction, resulting in an even more rapid build-up of torque and truly effortless acceleration.

Like the four-cylinder Ingenium diesel engines, this V6 is equipped with both high-pressure EGR and cooled low-pressure EGR systems and an SCR system to cut NOx emissions and ensure Euro 6 compliance.

Four-cylinder Ingenium petrol engines: performance and efficiency

Velar is one of the first applications for Jaguar Land Rover’s new 2.0-litre four-cylinder Ingenium petrol engines, designed to offer smooth, refined performance. Technologies including an integrated exhaust manifold, 200bar direct injection system and twin-scroll turbocharger are key to the engines’ responsiveness and efficiency.

The engines also feature electrohydraulic control of the inlet valves. This cutting-edge technology enables variable valve lift, so load control is managed primarily by the intake valves rather than the throttle. This reduces pumping losses and provides unmatched flexibility and control over airflow into the combustion chambers, improving power and torque, increasing fuel efficiency and reducing emissions.

Known as the P250, the first of the two new petrol engines develops peak power of 250PS and high maximum torque of 365Nm, which is maintained from just 1,200rpm to 4,500rpm. This means that Velar can accelerate from 0-60mph in 6.4 seconds (0-100km/h in 6.7 seconds) and return an impressive 37.2mpg (7.6-litres/100km) and 173g/km CO2 on the European combined cycle.

The most powerful version – the P300 – is rated at 300PS, making it the most powerful four-cylinder engine ever used in a Land Rover vehicle. It generates a maximum torque of 400Nm, delivering exceptional response at all times. This high-performance engine will be available later in the year.

Exceptional performance: Supercharged V6 petrol engine

The ultimate engine option for the most demanding drivers is the 3.0-litre supercharged V6. Known as the P380, this all-aluminium petrol engine is equipped with a Twin-Vortex supercharger, direct injection and dual-independent variable-camshaft timing to deliver instantaneous response from idle right up to the redline. Counter-rotating balancer shafts minimise vibration for exceptional refinement.

The result is an outstanding 380PS at 6500rpm and 450Nm of torque – enough to accelerate the vehicle from 0-60mph in just 5.3 seconds (0-100km/h 5.7 seconds) and on to an electronically-limited top speed of 155mph (250km/h). An impressive 30.1mpg (9.4-litres/100km) and 214g/km CO2 on the European combined cycle underline this powerful engine’s exceptional breadth of capability.

The unique exhaust note has been meticulously tuned to deliver an engaging but discreet confirmation of the power available to the driver on full throttle, and be superbly refined and relaxing at a cruise.

Smooth and responsive eight-speed automatic transmissions

Every Velar is equipped with a responsive and smooth eight-speed ZF automatic transmission with paddleshift controls. Four-cylinder engines are matched to the 8HP 45 transmission, which feature an integral pendulum damper. This device dramatically reduces the booming and vibration typically experienced when running in high gears at low engine speeds, and therefore contributes to Velar’s low fuel consumption and quiet, refined cabin.

The six-cylinders are paired with the 8HP 70 transmission, which is engineered to manage the higher torque ratings of these larger displacement engines. All engines benefit from bespoke transmission calibrations, ensuring optimum fuel efficiency and the most rewarding and intuitive shift characteristics.

3.3 Lightweight Aluminium Architecture: stiff, strong, safe

Velar’s aluminium-intensive monocoque body is developed using Jaguar Land Rover’s Lightweight Aluminium Architecture. This modular design, which features an intelligent mix of materials, is fundamental to Velar’s refinement, efficiency and all-terrain capability. Aluminium alloys account for more than 81 per cent of the body-in-white – a figure no competitor can match.

Carefully selected grades and types of materials are specified throughout the structure to deliver the optimum balance of strength, stiffness and weight. The use of 6000-series high-strength aluminium alloy bodysides enabled a reduction in panel thickness from 1.5mm to 1.1mm, saving weight without compromising strength. The aluminium roof helps to lower the centre of gravity, improving ride and handling. High-pressure die castings are used to form highly complex parts such as the front suspension turrets.

High-strength steels are used for selected rear body sections, and are joined to the adjacent aluminium panels with self-piercing rivets and structural adhesive. This clean and energy-efficient joining technology contributes to the body’s high torsional stiffness.

Lightweight magnesium alloys are used to make the front-end carrier and cross-car beam, while the tailgate is made from advanced composite materials.

Velar’s body structure also delivers high levels of crash protection safety was developed to meet the most demanding crash tests regulations worldwide. The protection afforded by the extremely rigid passenger cell is complemented by a restraints system featuring six airbags: driver and passenger airbags, side airbags that deploy from the front seats and curtain airbags spanning the front and rear seats.

Pedestrian impact protection was a priority too, and the material grade and form of the aluminium bonnet were developed to ensure progressive absorption of energy and optimised clearance from hard points in the engine compartment.

Aerodynamically-efficient: the most streamlined Land Rover

Velar’s aluminium-intensive form is not just light and stiff: it’s also exceptionally streamlined. Close collaboration from the outset between the Design and Engineering teams, together with exhaustive computational fluid dynamics simulation and wind tunnel testing, delivered a drag coefficient from just 0.32. This makes Velar the most aerodynamic Land Rover, and contributes significantly to its exceptional refinement and fuel efficiency.

Every last detail has been honed in order to let Velar pass through the air with minimal resistance: for example, even the ridge on the taillights has been designed induce clean separation of airflow from the bodysides, which in turn results in a cleaner wake structure and therefore reduce drag. Specially-designed air channels in the rear spoiler both cut drag and the accumulation of dirt on the rear screen – by up to 90 per cent.

Active vanes for the lower cooling aperture remain closed during the engines’ warm up phase, allowing it to reach operating temperature more quickly. But the vanes also close in conditions when additional cooling is no longer required – such as a steady-state cruise – which also reduces drag. Apertures in the front bumper direct air around the front wheels to reduce turbulence, contributing to further drag reductions.

The flow of air around the vehicle has been optimised in terms of lift too: as a result, the lift balance front-to-rear is an ideal 50:50, helping to further improve stability and steering feel at higher speeds, delivering even greater driver confidence.

Land Rover "E Glaze" Bullshit!

Post by Lancer » Mon Mar 06, 2017 12:22 pm

Dealer wants to put on that spoof glaze which they say covers the seats and paintwork with so-called "protection". Costs £350 ! Every Audi/BMW/Porsche Ive had has had this oh-so-necessary (NOT!) extra. What do people think?

Regarding the active Vanes:

Active vanes for the lower cooling aperture remain closed during the engines’ warm up phase, allowing it to reach operating temperature more quickly. But the vanes also close in conditions when additional cooling is no longer required – such as a steady-state cruise – which also reduces drag. Apertures in the front bumper direct air around the front wheels to reduce turbulence, contributing to further drag reduction

I pulled the VIN number of my soon to be delivered P380 HSE R-Dynamic: "LESS ACTIVE VANES", Less means not present.
